Cast-Iron Patty Melts

• 份量: 4 servings
• 总时间: 40 minutes

配料

1 Tbsp. olive oil

1 large onion, thinly sliced

2 tsp. kosher salt, divided

1 Tbsp. Worcestershire sauce

1 lb. ground chuck

8 slices rye bread

4 Tbsp. mayonnaise

4 (1 oz.) slices white American cheese, torn in half

4 (1 oz.) slices Swiss cheese, torn in half

4 Tbsp. salted butter, divided

步骤

Heat olive oil in a large cast iron skillet over medium. Add onions and 1 teaspoon salt; cook 20 minutes, stirring often, until well browned. Transfer onions to a medium bowl and stir in Worcestershire sauce. Do not wipe pan clean.

While onions cook, divide ground beef into 4 portions. Press each into a thin patty the same size as the bread between two pieces of parchment paper. Sprinkle evenly with remaining 1 teaspoon salt.

Cook patties two at a time, pressing slightly, until just barely pink in the middle, about 2 to 3 minutes per side. Remove from pan and wipe pan clean.

Assemble sandwiches. Spread a thin layer of mayonnaise on the outsides of each piece of bread. Divide American cheese slices among 4 slices rye bread, spacing evenly on the bread slices. Top each with a burger patty, 1/4 of the cooked onions, and Swiss cheese slices. Finish with remaining bread slices.

Melt 2 tablespoons butter in pan. Add 2 sandwiches and cook over medium until browned on each side and cheese has melted, about 3 to 4 minutes per side. Repeat with remaining sandwiches and serve immediately.
